I would not jump to conclusions yet. Often, things don't deliver all that they promise. In the case of USB for example, USB 2 is terrible when it comes to reliability. I did backups like 3 years ago to Terabyte Drives connected over USB 2.0 and although the speed was terrible, there was another problem: USB kept disconnecting when transfering about a terabyte over it, sometimes it worked, but sometimes during the transfer, at 600 or 800 gb, it just disconnected and the whole backup went to hell. Needless to say, it always happened when I was gone and when I came back, the waiting for all for nothing.

Whenever people rely a lot on external USB drives, and expect them to perform flawlessly (as you initially would), I flinch.

eSata is by the way exactly the same as SATA, just a slightly different connector (for external)
And if USB 3.0 stands up to heavy use (transfering lots and lots of data over it), only heavy use will show ;-)

I'm cautious at that point.
Also, the transfer rates that USB (any version) states in the specs are not guaranteed, especially not constantly. That is why for example digital camcorders could never be used over USB 2.0, but only over firewire.

Of course with SDcards and fully digital video (no more streaming from MiniDV tapes) this point has become moot.
